Connor F.R. Noise

2nd edition. — Edward Arnold, 1982. — 135 p.This is an introductory book on the important topic of Noise. Electrical noise is of considerable importance in communication systems and the book presents basic ideas in a coherent manner. Moreover, to assist in the understanding of these basic ideas, worked examples from past examination papers are provided to illustrate clearly the application of fundamental theory. The book begins with a survey of the various types of electrical noise found in communication systems and this is followed by a description of some mathematical ideas concerning random variables; Circuit noise, noise factor, and noise temperature are considered in the following chapters, and the book ends with a comparative study of some important communication systems.
In this new edition, certain parts of the text have been extensively revised. A new section on random variables is introduced in Chapter 2 and some basic ideas concerning matched filtering, decision theory, and estimation theory are presented in Chapter 3. A further treatment of circuit noise is made in Chapter 4 and a new section on low-noise amplifiers is included in Chapter 5. In Chapter 6, a comparative study of the signal-to-noise performance of various systems has been extended to cover digital systems and satellite systems. As an alternative approach, the energy-to-noise density ratio and its effect on the bit error rate is also included. A further feature of the book is the extended use of appendices to cover such topics as narrowband noise, decision theory, estimation theory, and the probability of error. It is intended for the reader seeking a deeper understanding of the text and is supplemented by a large number of useful references for further reading. The book also includes several worked examples and a set of typical problems with answers.
